Abstract: Method for installation and replacement of a membrane and system for retaining membrane on a structure. A connecting member comprises at least one radial channel for receiving a first guiding strip of a membrane sheet further having a second guiding strip. A fastening mechanism is provided for adjusting tension in the sheet by controlling depth at which the connecting member is maintained within a top channel on a truss of the structure. The tension may be adjusted by applying torque to bolted screws maintaining the connecting member into the top channel. Replacing the membrane sheet under tension involves unfastening, at least partially, the connecting member from the top channel to remove tension in the sheet and removing the sheet to be replaced from the connecting member and a second connecting member maintained on another truss.

Granted: 2021-11-23
Abstract: A system and method are presented for using spoken word verification to reduce false alarms by exploiting global and local contexts on a lexical level, a phoneme level, and on an acoustical level. The reduction of false alarms may occur through a process that determines whether a word has been detected or if it is a false alarm. Training examples are used to generate models of internal and external contexts which are compared to test word examples. The word may be accepted or rejected based on comparison results. Comparison may be performed either at the end of the process or at multiple steps of the process to determine whether the word is rejected.

Granted: 2019-01-15
Abstract: The present invention provides a technique capable of satisfying both the restoration of an output voltage of a fuel cell and an improvement of electric power responsiveness in a fuel cell system in a situation in which its operation status is restored to a normal operation from an operation having low power generation efficiency. A controller updates a lower limit voltage threshold in accordance with the restoration of an FC voltage until the operation status is restored to a normal operation from an operation having low power generation efficiency, such as an intermittent operation and a warm-up operation (step S1). The controller increases an FC current in accordance with the updated lower limit voltage threshold (steps S2 and S3) to thereby satisfy both the requirements of the restoration of the output voltage of the fuel cell stack and the improvement of the electric power responsiveness.
